固定式鑄鋼電動開關型球閥

產品介紹

Q947H電(dian)動浮動球閥采用硬密(mi)(mi)封(feng)(feng)結構，設計有(you)(you)工作(zuo)(zuo)密(mi)(mi)封(feng)(feng)和檢修(xiu)密(mi)(mi)封(feng)(feng)，操作(zuo)(zuo)力矩小，密(mi)(mi)封(feng)(feng)比壓適中，密(mi)(mi)封(feng)(feng) 可靠，動作(zuo)(zuo)靈敏，液動控制(zhi)易于實現自動控制(zhi)，使用壽命長，球閥的壓力溫度額(e)定值不僅與(yu)殼體材料(liao)(liao)有(you)(you)關，而且更多地與(yu)閥座、填料(liao)(liao)及墊片等密(mi)(mi)封(feng)(feng)件(jian)材料(liao)(liao)有(you)(you)。廣泛使用于石(shi)油(you)、化工、冶金、造紙(zhi)、制(zhi)藥、電(dian)鍍等行業(ye)

二(er)、固(gu)定式(shi)電動硬密封球閥外形及結(jie)構

結構特點

1、流體阻(zu)力(li)小，球閥(fa)(fa)是(shi)所有閥(fa)(fa)類中流體阻(zu)力(li)zui小的一種(zhong)，即(ji)使(shi)是(shi)縮(suo)徑球閥(fa)(fa)，其流體阻(zu)力(li)也(ye)相當(dang)小。

2、開關迅速(su)、方便，只(zhi)要閥桿轉動90°，球閥就完成了全開或(huo)全關動作，很容易(yi)實現快速(su)啟閉。

3、密(mi)(mi)封(feng)性(xing)(xing)能好。球閥(fa)閥(fa)座(zuo)密(mi)(mi)封(feng)圈一般采用聚四氟(fu)乙烯(xi)等彈性(xing)(xing)材(cai)料(liao)制造，易于(yu)保證密(mi)(mi)封(feng)，而且球閥(fa)的密(mi)(mi)封(feng)力隨(sui)著介質(zhi)壓(ya)力的增加(jia)而增大。

4、閥(fa)桿(gan)密封(feng)可靠。球閥(fa)啟閉(bi)時閥(fa)桿(gan)只作旋轉(zhuan)運動(dong)，因此閥(fa)桿(gan)的填(tian)料密封(feng)不易被(bei)破壞，而(er)且閥(fa)桿(gan)倒密封(feng)的密封(feng)力隨著介質(zhi)壓(ya)力的增加(jia)而(er)增大。

5、球閥(fa)(fa)的(de)啟閉只(zhi)做90°轉動(dong)，故容易(yi)實現自動(dong)化控制(zhi)和遠距離控制(zhi)，球閥(fa)(fa)可(ke)配(pei)置(zhi)氣動(dong)裝(zhuang)(zhuang)(zhuang)置(zhi)、電動(dong)裝(zhuang)(zhuang)(zhuang)置(zhi)、液(ye)動(dong)裝(zhuang)(zhuang)(zhuang)置(zhi)、氣液(ye)聯動(dong)裝(zhuang)(zhuang)(zhuang)置(zhi)或(huo)電液(ye)聯動(dong)裝(zhuang)(zhuang)(zhuang)置(zhi)。

6、球閥(fa)通(tong)道(dao)平整光滑(hua)，不易沉積(ji)介質(zhi)，可以進行管線通(tong)球。

貝爾鄭重承諾：產品(pin)(pin)出廠前均已經過各項嚴(yan)格品(pin)(pin)質管制(zhi)作業及性能試驗，自即日起在正常使用狀況下(xia)保(bao)固一年。但非人力所(suo)能抗(kang)拒之災害，外力破壞，及未經本公司同意而私自拆卸者不在保(bao)固范圍(wei)之列。
